SPRING, Texas (AP) — A 17-year-old male student has been charged with murder in a deadly knife fight at a Houston-area high school.

A Harris County Sheriff’s Office statement says Luis Alonzo Alfaro was charged in the fight at Spring High School that killed a student Wednesday.

The stabbing happened during a fight between several students in a school corridor. The sheriff’s statement says that during the fight, Alfaro pulled a knife and stabbed a 17-year-old student to death and wounded three other students. The three survivors were treated at a hospital and discharged.

The statement says Alfaro admitted the stabbing under questioning by sheriff’s homicide detectives.

School district officials have canceled classes at the high school for the rest of the week.
